Jewish Thought on the Trinity and the Godhead

In contemporary Judaism, the standard position is to reject the Christian doctrine of the Trinity. From the point of view of mainstream rabbinic Judaism—whether Orthodox, Conservative, or Reform—the Trinity is not regarded as compatible with their understanding of the oneness of God as expressed in the Shema:

"Hear, O Israel: The LORD our God is one LORD."

This confession in Deuteronomy 6:4 is taken as a categorical assertion of numeric unity in a way that excludes any notion of three distinct persons within the Godhead. Jewish apologists such as Rabbi Tovia Singer, for example, argue that the Christian Trinity is either a later theological development influenced by Greek categories or a misreading of the Hebrew scriptures. They would typically assert that the Trinity violates both the plain sense of the Shema and other biblical declarations of God’s uniqueness and incomparability.

So, yes, the Jewish view is different from the average Christian view. Christianity’s classic Trinitarianism teaches that the one God eternally exists in three distinct persons—Father, Son, and Holy Spirit—each fully God, sharing the same essence, yet personally distinct. Modern Judaism, in contrast, emphasizes an indivisible oneness and ordinarily regards any notion of God being incarnate in an individual (such as Jesus) as a denial of that oneness.

Historical Nuances: Godhead in Biblical Judaism

However, that is not the whole story. When you look back into what we might call "biblical Judaism"—the faith of the Old Testament and the interpretive world closest to the biblical text—there are indications that the picture was more complex than later Jewish reaction to Christianity might suggest.

One helpful term here is "Godhead" rather than "Trinity." Scripture uses "Godhead" (in English translations) to indicate the fullness of what God is, without necessarily specifying the later creedal formula of three persons. There are strands within the Old Testament that suggest plurality within the one God— such as the "angel of the LORD" who speaks as God, receives worship, and yet is distinguished from God, or the use of "LORD" speaking to "my Lord" in certain psalms.

Psalm 110:1 is a key example:

"The LORD said unto my Lord, Sit thou at my right hand, until I make thine enemies thy footstool."

Here, the first "LORD" (in many English Bibles in all caps) represents the Tetragrammaton—YHWH, the covenant name of God. The second "Lord" is a title of authority applied to someone distinct from YHWH, yet exalted to sit at His right hand and to share in His rule.

In later Jewish exegesis, such as in Rashi’s commentary, this second "Lord" is often read as a human figure such as Abraham, partly to distance the text from Christian messianic claims. Rashi interprets the psalm as the word of the LORD to Abraham, whom the nations called "my master." Other post-biblical Jewish readings sometimes refer the psalm to David or to some other national figure, but they very intentionally avoid the interpretation that makes this second "Lord" a preexistent, exalted Messiah of a nature shared with YHWH.

By contrast, in the New Testament, this verse is taken explicitly as messianic. Peter, preaching on the day of Pentecost, cites Psalm 110:1 in Acts 2:34–36:

"For David is not ascended into the heavens: but he saith himself, The LORD said unto my Lord, Sit thou on my right hand, Until I make thy foes thy footstool. Therefore let all the house of Israel know assuredly, that God hath made that same Jesus, whom ye have crucified, both Lord and Christ."

Peter’s argument presupposes that his Jewish audience will recognize that "my Lord" in Psalm 110:1 refers to someone other than David himself; "David is not ascended into the heavens." He then identifies that exalted "Lord" with Jesus, whom God has made both "Lord" and "Christ." Notably, there is no recorded outcry that Peter has misused a text that everyone knew belonged to Abraham or to some purely human figure. That suggests that, at least in the apostolic era, many Jews were open to, or at least familiar with, a reading of Psalm 110 that saw a transcendent, exalted Lord distinct from yet related to YHWH.

This is one example among others (for instance, the "Son of Man" vision in Daniel 7, the angel of the LORD narratives, and certain wisdom passages) that can be marshaled to argue that ancient Judaism had conceptual room for some form of plurality within the Godhead, even if it did not codify this in the later Trinitarian formula. The New Testament’s claims about Jesus as the Son of God and as sharing the Father’s glory and authority did not come out of a vacuum; they engage themes already present in the Hebrew scriptures.

Post-Christian Jewish Reaction

After the rise of Christianity and its claims about Jesus as the incarnate Son of God, Jewish theology developed, in part, in self-conscious distinction from these claims. Texts that Christians used to argue for the Messiah’s exalted, more-than-human status increasingly received alternative readings within Judaism, and interpretations that would sound too much like "plurality within God" were often treated with suspicion.

The result is that much of modern Jewish theology about God, including its rejection of the Trinity, is not a simple continuation of Old Testament theology untouched by subsequent controversies. It is, in many respects, a post-Christian construction aimed at heading off what Jews came to see as Christological and Trinitarian misreadings of their scriptures. From their perspective, this is a defense of pure monotheism. From a Christian perspective, it can be seen as a reaction that, in guarding against Christian claims, sometimes closes off interpretive options that the biblical text itself had left open.

Summary of the Contrast

So in contemporary terms:

• Standard Jewish position: God is absolutely one; the Trinity is rejected as incompatible with the Shema and with the Jewish understanding of monotheism. Any notion of incarnation or of a divine Messiah who is personally distinct from the Father is likewise rejected.
• Typical Christian position: God is one in essence and three in person—Father, Son, and Holy Spirit. Old Testament passages such as Psalm 110:1, along with many others, are taken to reveal or anticipate this plurality within unity, and the New Testament identifies Jesus as the exalted "Lord" seated at the right hand of the Father.

There is thus a clear difference at the doctrinal level today. Yet when you go back into the scriptural and early Jewish materials, you find more evidence for a complex, richly textured view of the Godhead than modern Jewish polemics against the Trinity generally admit. That earlier complexity is exactly what the New Testament seizes upon when it presents Jesus as Lord, Christ, and the one seated at the right hand of God.
